  • During Pandemic, Science Still Going and ARM Data Still Flowing

    Patience rewards one delayed Alaskan field campaign studying ice fog Editor’s note: This is the first article in a series looking at how ARM has continued to support atmospheric science during the pandemic. During a tethered balloon flight for the Ice Fog Field Experiment at Oliktok Point (IFFExO) in November 2020, a laser shines from…

  • VAP for 3-Channel Microwave Radiometer Retrievals Released to Production

    This Microwave Radiometer Retrievals version 2 (MWRRETv2) quicklook image is from Oliktok Point, Alaska, on February 8, 2018. From top to bottom, panels show observed brightness temperatures at 23.8 (blue), 30 (red), and 89 GHz (green); physically (red and blue) and statistically (green) retrieved precipitable water vapor; physically (red and blue) and statistically (green) retrieved…

  • New Radiation Data Quality (QCRAD) VAP Release Now Available

    A broadband radiometer station at ARM’s Southern Great Plains Central Facility near Lamont, Oklahoma, measures broadband solar (shortwave) and infrared (longwave) radiation. Data from this station have been processed as part of a new release for the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product. A new level 2 (c2/s2) release for the…

  • QCRAD Value-Added Data Product Updates Available

    Level 2 (c2/s2) data for the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product (VAP) have now been processed at all Atmospheric Radiation Measurement (ARM) user facility fixed sites through summer 2017. These sites include the Southern Great Plains central and extended facilities, Barrow (known officially as Utqiaġvik) and Oliktok Point, Alaska, and…

  • Aerosol Optical Properties VAP Now Available

    The first plot shows the aerosol extensive property of light absorption for nominally “red,” “green,” and “blue” light over a two-week period at Ascension Island. The second plot shows the wavelength dependence of aerosol absorption—an intensive property—which describes the nature rather than the abundance of the absorption. The Aerosol Optical Properties (AOP) value-added product (VAP)…

  • Multi-Angle Snowflake Camera Value-Added Product Now Available

    Retrieved average of maximum dimension for a subset of particles that fell into each 5-minute wide time bin (top) and quality bits (bottom) for data captured between May 13 and May 19, 2016, are shown here. The Multi-Angle Snowflake Camera (MASC) instrument provides high-resolution multi-angle imaging of hydrometeors in free fall with simultaneous measurement of…
